What is a tropical depression storm?
A tropical depression is a tropical cyclone that has maximum sustained surface winds (one-minute average) of 38 mph (33 knots) or less. Tropical Storm. A tropical storm is a tropical cyclone that has maximum sustained surface winds ranging from 39-73 mph (34 to 63 knots).
What is Tropical Cyclone classification?
TROPICAL STORM (TS) – a tropical cyclone with maximum wind speed of 62 to 88 kph or 34 – 47 knots. SEVERE TROPICAL STORM (STS) , a tropical cyclone with maximum wind speed of 89 to 117 kph or 48 – 63 knots. TYPHOON (TY) – a tropical cyclone with maximum wind speed of 118 to 220 kph or 64 – 120 knots.
What is a Category 6 cyclone?

How are cyclones Categorised?
In order for it to be categorised as a cyclone, its average sustained wind speed needs to exceed 63 km per hour. To be classified as severe, the average sustained wind speed needs to exceed 118 km per hour. Once a cyclone arrives over land, its strength weakens and it begins to fade out.
How are tropical cyclone intensity classified?
cyclones are classified on the basis of the wind speed. The lowest official classification used in the North Indian Ocean is a Depression, which has 3-minute sustained wind speeds of between 20–31 mph (31–49 km/h).
